Given numbers are 644, 421, 668, 326

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(644, 421) = 271124

GCD(644, 421) = ( 644 x 421 ) / 271124

= 644 / 421

= 644

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

So, Greatest Common Divisor of 644, 421, 668, 326 is 1
